The largest operating businesses engage in loan servicing and education technology, services, and payment processing, and the Company also has a significant investment in communications. A significant portion of the Company's revenue is net interest income earned on a portfolio of federally insured student loans. The Company also makes investments to further diversify the Company both within and outside of its historical core education-related businesses, including, but not limited to, investments in early-stage and emerging growth companies, real estate, and renewable energy (solar). Substantially all revenue from external customers is earned, and all long-lived assets are located, in the United States.</span></div><div style="margin-bottom:9pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company was formed as a Nebraska corporation in 1978 to service federal student loans for two local banks. The Company built on this initial foundation as a servicer to become a leading originator, holder, and servicer of federal student loans, principally consisting of loans originated under the Federal Family Education Loan Program (“FFELP” or “FFEL Program”) of the U.S. Department of Education (the “Department”).</span></div><div style="margin-bottom:9pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Health Care and Education Reconciliation Act of 2010 (the “Reconciliation Act of 2010”) discontinued loan originations under the FFEL Program, effective July 1, 2010, and requires that all new federal student loan originations be made directly by the Department through the Federal Direct Loan Program. This law does not alter or affect the terms and conditions of existing FFELP loans. As a result of this law, the Company no longer originates FFELP loans. However, a significant portion of the Company’s income continues to be derived from its existing FFELP student loan portfolio. Interest income on the Company’s existing FFELP loan portfolio will decline over time as the portfolio is paid down. Since all FFELP loans will eventually run off, a key objective of the Company is to reposition itself for the post-FFELP environment. To reduce its reliance on interest income on student loans, the Company has expanded its services and products. This expansion has been accomplished through internal growth and innovation as well as business and certain investment acquisitions. The Company is also actively expanding its private education and consumer loan portfolios, and in November 2020 launched Nelnet Bank (as further discussed below). In addition, the Company has been servicing federally owned student loans for the Department since 2009.</span></div><div style="margin-bottom:9pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company's reportable operating segments include:</span></div><div style="text-align:justify;text-indent:31.5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:1pt"> Loan Servicing and Systems (“LSS”)</span></div><div style="text-align:justify;text-indent:31.5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:1pt"> Education Technology, Services, and Payment Processing (“ETS&PP”)</span></div><div style="text-align:justify;text-indent:31.5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:1pt"> Communications</span></div><div style="text-align:justify;text-indent:31.5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:1pt"> Asset Generation and Management (“AGM”)</span></div><div style="margin-bottom:9pt;text-align:justify;text-indent:31.5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">•</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;padding-left:1pt"> Nelnet Bank</span></div><div style="margin-bottom:9pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">A description of each reportable operating segment is included below.
